I appreciate all your comments.   It helps me better understand what I 
am dong.    In fact I do dynamically build my ZClasses on the fly on the 
production server.  When I build a new job board, a whole bunch of stuff 
gets automagically done.   I have code writing code.  Then the users 
create specific instances of ZClasses. 

I love the idea that Zope 3 includes schema information.  I love the 
idea of building Zope 3 schemas through the web.   But Legacy code and 
data has a powerful gravitational pull.   I have a working application, 
it is very little work to make the upgrades I need to make.  It is a 
huge amount of work to migrate it to Zope 3. 

If I built a new application, it would be in Zope 3.  For the existing 
stuff I am happy enough with Zope 2.  It is so much better than PHP!

In terms of motivations, I am happy enough with Zope 2.7*  I do not 
really understand the new upgrades, or what the changes are, or what the 
benefits are.   With all due respect, I would prefer stability in my 
platform rather than evolution.

At some point I will come up with a limitation of Zope 2.7*, I will need 
to upgrade, ZClasses will not be working, and I will then do something.

In the meantime my attention is much more focussed on how to manage my 
employees better using my application. 

Thanks for all the advice.   I expect you will hear back from me when 
ZClasses are next discussed on this mailing list.
